Definitions

  • the invention relates to a device for stripping excess seed grains according to the preamble of claim 1.
  • a device for stripping excess seeds is for example in the EP 0 598 636 B1 described.
  • the scraper elements are formed as pins and arranged on a pivotally mounted lever.
  • On the lever is a rotatable roller which comes to rest on the drum to ensure that the ends of the pins of the Abstreiferimplantation comply with the prescribed distance from the drum.
  • the FR 2 641 441 A1 shows a device for stripping excess grains.
  • the scraper elements are formed as lamellae. In one embodiment, they can be partially elastic or, in another embodiment, be brought into contact with the drum by means of a sliding guide loaded with a spring.
  • the invention has for its object to provide a simply ausgestaltetes and leaning against the drum outer contour scraper element.
  • the stripper region forming and consisting of an elastic region segment of the scraper element is arranged on a holder made of stiffer or solid material.
  • a particularly good design of the wiper area results from the fact that the wiper area is lip-shaped.
  • the scraper element is arranged fixedly.
  • the separating device formed as a separating drum 1 is rotatably mounted in the housing 2 partially shown and driven in rotation.
  • the separating drum 1 is associated with a storage container, not shown, and an air pressure generating device, for example a blower.
  • the sowing openings 3 are arranged in several circumferential circular rows arranged, wherein the seeding openings 3 are acted upon by the pressure generating means with a pressure difference, so that the seeds located in the seed stock 4 of the reservoir can accumulate due to the pressure difference at the seeding openings 3.
  • a negative pressure or on the outside of the drum an overpressure can be generated, so that the seeds on the outside of the drum 1 to the sowing holes 3 due to the generated pressure difference accumulate.
  • the scraper elements 5 At a distance to the huirungs Surrey, that is, to the area in which the seed drum 1 is passed through the seed stock 4, on the outside of the drum 1, the scraper elements 5 having several scraper elements 6 is arranged. Each row of sowing openings 3 is assigned a scraper element 5.
  • the scraper elements 5 are made of an elastic material at least in the region 6 resting against the drum 1.
  • the scraper element 5, which consists at least partially of an elastic material 6, is designed to be flexibly adapting to the drum or disk contour of the drum 1. Due to the inherent elasticity of the scraper element 5 this spring-loaded against the drum 1 is arranged adjacent.
  • the scraper region 6 of the scraper element 5 is lip-shaped.
  • the segment 7 of the stripper element 5 forming the stripper area 6 and made of an elastic material is attached to a holder 8 made of a stiffer or more solid material arranged.
  • These two areas 6, 7 and 8 may be formed in one piece or of two sections exist, which are connected to each other for example by gluing or other fasteners.
  • the individual scraper elements 5 are arranged on a common holder 9 and can be adjusted together relative to the sowing openings 3. In this case, the adjustment takes place so that too much seed grains attached to each sowing opening 3 are stripped off so that only one seed grain is deposited on the respective sowing opening 3 of a row after passing through the respective stripper element 5.
